Very impressive! It looks great, and the performance is quite good on Win10 here. What algorithm do you use to create the height map?

Thanks! I'm not happy with the trees, they are 4 Tris LOD ones, supposed to be replaced by a detailed versions on close distance, but I never added that. It is in the original generator walk-through mode tho, that's in Blitz3D for windows.
The height map is loaded as bmp, greyscale. If not found, a simple random map is made, using some weird mixture of sinus,random,noise and smoothing.
